Title: Installation for loading and unloading an inland-waterway vessel with heavy-load railway wagons
Inventor: DE LORENZIS RENATE
IPC: B63B27/00
Filed: 1990-02-19
Abstract: ABSTRACT OF THE DISCLOSURE:           In order to transport heavy-load railway wagons, in particular mixer-type hot-metal wagons, on inland-waterway vessels,  it is proposed that the vessels be fitted with a railway track running from bow to stern above the loaded waterline.   Used for loading and unloading is a lock chamber located at the loading station or the unloading station on a navigable waterway.  These lock chambers are equipped with devices for raising and lowering the water level and have a step over which the vessel can be traversed with the lock chamber flooded and on the floor of which the vessel can lie when the water level is lowered, the track on the vessel joining up with a land-based access line so that wagons can be moved by rail on to or down into the vessel.  On completion of loading or unloading, the lock chamber is flooded again so that the vessel can be traversed off the step and, by lowering the water level, brought to the level of the water in the waterway and permitted to leave th elock chamber.

Title: Seismic expansion joint cover
Inventor: MOULTON PAUL
IPC: E04B1/68
Filed: 1991-12-23
Abstract: A seismic expansion joint cover comprises a pair of elongated frame members, each of which is adapted to be secured to a building member, one on one side of an expansion gap and the other on the other side of the expansion gap, and each of which has a planar support surface and an edge adapted to overhang the gap. An elongated cover member spans the expansion gap and is supported on the support surfaces of the respective frame members for sliding movement of the frame members relative to the cover member. A hold-down assembly resiliently holds the cover member in engagement with the support surfaces of the frame members. A multiplicity of deflector members on the cover member, each having an inclined surface that is engageable by the overhanging edge of one of the frame members upon narrowing of the expansion gap during a seismic event, is adapted upon such engagement to displace the cover member against the bias of the hold-down assembly to a position in which its side edges are not susceptible to contact with any portions of the frame members or the building members upon further narrowing of the expansion gap. Gaskets are detachably connected to the side edge of the cover member and to the frame members.

Patent CA-2068010-A1 (CA)
Inventor: ENG ROBERT C
IPC: G06F13/362
Filed: 1992-05-05
Abstract: Methods and apparatus are set forth which optimize and balance the use of processor card (or complex) resources (e. g., memory, the local bus, etc .), with the use of other system resources, such as the card to card communications bus and devices attached thereto, in dual bus computing systems. A new data rate management technique reduces data transfer overhead particularly for burst mode transfers. The invention promptly services pending memory refresh requests; limits multiple accesses to on card (or processor complex) memory by an Alternate Bus Master to a predetermined number of cycles where the processor requests the use of its local bus; and allows an Alternate Bus Master unlimited accesses to the processor local bus when the Alternate Bus Master owns the card to card communications bus and the processor subsequently requests that bus. The aforementioned balance of resources is achieved using a Bus Hold On Grant ("BSHOG") scheduling procedure which, assuming a bursting Alternate Bus Master has gained control of the local processor bus and is conducting data transfer cycles when the processor requests the local bus, allows the Alternate Bus Master to conditionally retain local bus ownership over a plurality of Alternate Bus Master data transfer cycles.

Title: Adsorbent vessel having a convective heat exchanger and flow developer
Inventor: TOPPEL KARL O
IPC: B01J8/02
Filed: 1992-06-25
Abstract: Abstract The present invention provides an adsorbent vessel adapted to contain an adsorbent and form an adsorbent bed for use in adsorbing a component of a multicomponent gas mixture during a pressure swing adsorption process.   In accordance with  such process  the  adsorbent  bed is  regenerated  by  desorbing  the adsorbed component.  The adsorption capacity of the adsorbent decreases with decreasing temperature and the pressure swing adsorption process produces a cold spot of reduced temperature within a region of the adsorbent bed.  In order to combat the resulting  decreased  adsorption  capacity,  a  convective  heat exchanger extends into the cold spot to raise the temperature of the cold spot.  The convective heat exchanger is provided with at least two passes for the entering multi-component gas mixture or the outward bound desorbed component to transverse and thereby transfer heat to the cold spot.  Additionally, the heat exchanger can also serve to supply a  sufficiently long straight run for the entering multi-component gas mixture to fully  develop.   The  full  development  of  the  entering  flow prevents  unequal  distribution of  the  multi-component  gas mixture within the adsorbent bed.

Title: Video system with feedback controlled "white stretch" processing and brightness compensation
Inventor: LAGONI WILLIAM A
IPC: H04N5/20
Filed: 1992-10-15
Abstract: A non-linear (e.g., "white stretch") processor and a brightness control processor are coupled in cascade between an input for receiving a video input signal to be processed and an output for providing a processed video output signal. A control signal for controlling the transfer characteristics of the non-linear processor is provided by an amplifier having a first input coupled to receive an average picture level (APL) indicating signal derived from the processed video output signal and having a second input coupled to receive a reference level signal supplied thereto. A brightness control signal is applied to a control input of the brightness control processor for controlling the brightness level of the processed video output signal. Circuit means are provided for deriving at least a portion of the reference level signal for the amplifier from the brightness control signal supplied to the brightness control processor thereby reducing a tendency for variations in the brightness control signal to alter the transfer characteristics of the non-linear processor.

Title: Repeaters for digital data networks
Inventor: ADAMS MARTIN CHARLES
IPC: H04L12/931
Filed: 1992-03-30
Abstract: A multiport repeater for a data network operating on a CSMA or CSMA/CD protocol, for example an Ethernet local area network, has signals transmitted from port to port via a crosspoint switch or other appropriate switching means. The destination address of each incoming data frame is read and compared with a stored table to determine which port or ports the frame needs to be transmitted to, and the switching means is then operated to cease transmitting the frame unnecessarily to other ports. The remaining ports are thus returned to an idle state, and a second frame overlapping with the first can be received and retransmitted provided it does not require any of the ports that are in use in transmitting the first frame. If the second frame does require one of the ports that are already in use, then a collision signal is returned and the source station will stop transmission in the normal way, after which the switching means is reset to respond appropriately when the source station re-tries (or another signal is received).
